Application filed January 2, 1915. Serial No. 72.

To all whom it may concern Be it known that we, Mosns MosLnR, a citizenof the United States, residing at Cincinnati, Hamilton county, Ohio, andCARL BARTELS, a citizen of the United States, residing at Hamilton,Butler county, Ohio, have invented certain new and useful Improvementsin Safe Construction, of which the following is a specification.

This invention, pertaining to safe construction, relates tothearrangement of an door carried by the main door and adapted to make aspecial closure with the inner compartment of the safe, the auxiliarydoor opening with the main door or remaining in closed condition whilethe main door is open, as desired.

The invention will be readily understood from the following descriptiontaken in connection with the accompanying drawings in which 2- v Figure1 is a front elevation of a safe exemplifying our invention, a lowerportion of the main door being broken away to expose the auxiliary doorin its rear, while an upper portion of both doors is broken away toexpose the jamb construction pertaining to both doors: Fig. 2 a frontelevation of the auxiliary door: Fig. 3 a plan of the auxiliary door, inconjunction with the couplingspurs carried by the main door, these spursappearing in horizontal section in the plane of line a of Fig. 8: Fig. 4a vertical section of the front portion of the safe in the plane of lineb of Figs. 1,2, 3, 5, 6 and 7: Fig.

5 a vertical section of the main door clutch in the plane of line 0 ofFigs. 4 and 7: Fig. 6 a front elevation of portions of the lockingmechanism, the main door clutch appearing in vertical section in theplane of line (Z of Figs. 4 and 7: Fig. 7 a plan of portions of thelocking mechanism, the plates of the doors appearing in horizontalsection in the plane of line a of Figs. 1, 2, 4, 5 and 6: Fig. 8 aperspective rear view of the upper portion of the main door inconjunction with one of the locking bars of the auxilitary door movedaway from the main door: Fig. 9 a diagrammatic front elevation of aportion of the looking-dog in conjunction with one of the tumblers ofthe combination lock: and Fig. 10 a vertical section of a lower portionof the doors and inner safe compartment, in the plane of line f of Figs.1, 2 and 3.

A diversity of scales is employed in the drawings.

In the drawings :-1, indicates the front of the safe: 2, the steppeddoor-j amb thereof: 3, the inner compartment of the safe, the same to beformed in water-tight manner, as of metal with welded or brazed seams:4, the rear portion of the door-jamb, the same to be firmly secured tothe front portion of the walls of the inner compartment 3: 5, packing,of rubber or other suitable material, extending around within thedoorjamb and exterior to the front portions of the walls of the innercompartment 3, which portions extend forwardly beyond the jambportions 4to which they are secured: 6, teeth projecting inwardly, at spacedintervals, from a rear portion of the door-jamb forward of the frontedges of the walls of the inner compartment 3: 7 the main door,considered as a whole, this door fitting the steps of the jamb in theusual manner: 8, the front plate of the main door: 9, a back or innerplate of the main door, forming a rigid part thereof and designed tocarry such locking mechanism as pertains to the main door: 10, the stepsof the margin of the main door, fitting into the steps of the jamb, asusual: 11, the exterior handle for operating the locking bolts of themain door: 12, the combination lock, considered as a whole: 13, spacesin the door and safe walls which may be provided to receive the usualfire-proof filling: 14, the bolts of the main door: and 15, thecarrying-bar for these bolts.

All of the parts ing its bolts and and locking mechanism, in any usualor suitable far considered the main door would furnish the usualfire-proof protection but, as is well understood, the steps of thesedoors cannot fit with tightness within the steps of the jamb, theconsequence being that, in

of the main door includbolt-throwing mechanism may be constructedmanner. As thus case of flooding, water can get access to the interiorcompartment of the safe. In case the door isprovided with packing tosecure water-tightness, the water-tightness becomes lost when the maindoor becomes warped by the falling of the safe or by the action of waterupon it while heated. In the present invention the water-tightness issecured by means of an auxiliary door 00- operating with the front ofthe inner compartment and performing its functions in dependent of themain door.

Proceeding with the drawings :16,indi-- cates a plate seating againstthe front of the inner compartment 3 and forming the auxili-' ary door:17,bolt-bars fitted to slide on the front face of the auxiliary door,there being one of these bolt-bars at each edge of the auxiliary door:18, teeth projecting outwardly from the edges of these bars, these teethbeing adapted, while the door is being closed, to pass in betweenjambteeth 6 and take position to the rear of the jambteeth and then,when the bolt-bars are shifted endwise, to pass behind the jambteeth andwedge the auxiliary door tightly against the front of the innercompartment 3, the cooperating faces of teeth 18' and the jamb-teethbeing beveled to produce this wedging action as the bolt-bars are moved:19, levers pivoted upon the front face of the auxiliary door and havingtheir outer ends in engagement with bolt-bars 17, so that theoscillation of the levers will shift the bolt-bars endwise to looking orunlocking position: 20, a pinion journaled on the front face of theauxiliary door andhaving its teeth engaging teeth on the inner ends oflevers 19, so that the turning of the pinion will oscillate all of thelevers simultaneously: 21, a clutch-member formed on the front face ofthe pinion: 22, bellcranks pivoted to the auxiliary door and connectingthe contiguous ends of bolt-bars 17: 23, a rearwardly presenting hookcarried by the upper inner portion of the main door: 24, a forwardlypresenting hook carried by the front face of the auxiliary door andadapted, when the two doors are in association, to engage over hook 23of the main door: 25, a spindle journaled in the main door in axialalinement with pinion 20:

26, a clutch-member carried by the rear end of spindle 25 and adapted,when the two doors are in association, to engage with clutch-member 21carried by the auxiliary door: 27, a handle, exterior to the main door,to serve in'turning the spindle 25:

28, a packing carried by a groove in the rear face of auxiliary door 16,near its edge, and adapted to engage with the forward edges of the Wallsof inner compartment 3: 29, spurs projecting down from the inner upperportion of the main door 30, hooks carried at the front face of theupper one of bolt-bars 17 and adapted, when that boltbar is shifted tothe unlocking position, to v adapted, as the dog moves downwardly, to

engage in notch 31 and prevent the endwise shifting of the bolt-barprovided with that notch: 33, a toe on the outer end of dog 32 andadapted to ride on one of the bevels of the stepped door-jamb and holdthe dog up to inactive position when the doors are in closed position inthe doorjambz' 34, a pivoted dog-lever carried by the main door andhaving an end adapted to engage in notch 43 ofdoor-clutch 26 when thepinion is in angular position corresponding with the locked condition ofthe auxiliary door: 35, a prong carried by doglever 34 and adapted toenter the releasing notches of the tumblers of the combina tion lock;36, a tail-piece extended inwardly from the carrying-bar 15 of the boltsof the main door: 37, an incline on this tailpiece engaging an inclineon that end of lever 34 which carries prong 35: 38, a peripheral notchin clutch-member 26 of the main door: 39, a second similar notch in thisclutch-member: 40, a vertically sliding detent carried, by the rearportion of the main door near and radial to clutch-member 26: 41, atooth on the end of detent 40 adapted to engage notch 39 in onepositionof the auxiliary bolt-work and to engage notch 38 in another position ofthe auxiliary bolt-work: 42, an incline on tail-piece 36 of thecarrying-bar of the bolts of the main door, adapted to cooperate with anincline on detent 40 and move the detent toward clutch-me1nber 26 whenthe carrying-bar is retracted: and 43, the notch of the main door clutchwhich is engaged by one end of dog-lever 34.

All of the figures of the drawings with the exception of Fig. 8, assumeboth doors as being closed and bolted and that the combination lock hasbeen set up so as to permit of the unbolting of the doors.

A sume, now, that it is desired to open the safe completely. Handle 27is to be turned, with the sun, the setting up of the combination lockpermitting this, and the turning of the handle causes pinion 20 to moveboltbars 17 in the direction of the arrows 9 thus releasing their teeth-18 from the teeth 6 of the jamb. The auxiliary door is now unbolted fromthe jamb, and it is to be observed that the bolt-bars 17 will be movedsimultaneously by the four levers 19 and that they would bemoved'simultaneously in the lifting detent 40 and causing detent tooth41 to enter notch 38 in the main door clutch,

locked to the main this notch having been angularly advanced by theturning of the handle 27 which released the auxiliary door bolts.Incline 37 on the tail-piece of the carrying-bar is not essential but itserves to insure the completion of the movement of dog-lever 34 indisengagement from notch 43. This unbolting movement of bolt-bars 17 hascaused hooks 30 on one of these bolt-bars to engage in front of spurs 29carried bythe main door, the result being that the auxiliary door isdoor and cannot be imlocked therefrom until the bolts of the auxiliarydoor are again thrown. Both doors are now unbolted from the jamb and maybe opened, the auxiliary door coming with and forming virtually a partof the main door. As the compound door opens, the toe of dog 32 ridesoff of the bevel of the jamb and permits the dog to drop into notch 31.If, now, a meddling attempt be made to operate handle 27 and throw thebolts of the auxiliary door it cannot be done on account of thedetaining action of dog 32.

When the safe is pound door is pushed shut and the main door-boltsthrown by means of handle 11 and, if desired, the combination lock isthrown. This leaves the main door locked in the jamb but has no effectin moving the auxiliary door against the inner compartment, and it isdesirable, for the sake of conserving the life of the packing, not toput this packing into service except when the auxiliary door is to beput into its special service. When the safe, under these closedconditions, is to be opened, it is only necessary to set up thecombination lock and to draw the main door bolts.

Assume, now, that it be desired not only to close and bolt the main doorbut to close and bolt the auxiliary door. The compound door is to beclosed,'as in the case just mentioned, and the main door bolts thrown.The closing of the compound door has released dog 32 from notch 31,freeing the bolts of the auxiliary door. If an attempt be made to throwthe bolts of the auxiliary door before the main door bolts have beenthrown, the attempt will be defeated by the engagement of detent tooth41 in notch 38 of the main door clutch. But, the main door bolts havingbeen thrown, handle 27 may then be manipulated to throw the auxiliarybolts and causethe auxiliary door to to be closed, the commove a trifleaway from the main door and go into intimate water-tight contact withthe inner compartment of the safe. The throwing of the combination lockwill then look the compound door.

We have thus far explained the unbolting and opening of the compounddoor as a unit; the closing of the compound door and the bolting of themain door only; and the closing of the compound door and the bolting ofboth its components.

Assume, now, that it be desired to open the main door and leave theauxiliary door bolted to place. The combination lock having been set up,the main door bolts may be drawn and the main door opened, leaving theauxiliary door sealed against the front of the inner compartment of thesafe and firmly bolted, clutch member 26 of the main door separatingaway from clutch-member 21 of the auxiliary door. The main door havingthus been opened away from the auxiliary door gives access to thecombination lock and to the general bolting mechanism.

hen the main door bolts were drawn, preparatory to the opening of themain door without opening the auxiliary door, detent tooth 41 enterednotch 39 which insures that the angular position of the main doorclutchshall be such as to permit the clutchmembers to rengage when the maindoor is again closed against the auxiliary door.

We have chosen to illustrate our invention in a safe of square doorfireproof type, the auxiliary door having its bolting mechanism ofsliding toothed bar type, but it is to be understood that the particularconstruction set forth is but a single exemplification; of our inventionwhich may be realized in numerous modifications.

We have simply sought to explain the principle of our invention and toset forth the best form in which we at present contemplate embodyingthat invention.
